i have a go .28 and a mach .28, and i need to know which will be faster because i need to decide what one to put into my hyper st?

cheers

adam.

Since you own both of them try em out for yourself it's the only way to be sure.

yeh i was thinking of doing that, i just wanted to know if anyone had a definite answer to save me time lol.

cheers.

Is it for racing? If it is, you main concerns should be about dependability and runtime.

dotn race with the mach 28[:'(] ive had bad expeirences with them

yeh its for racing. i just took the go .28 out of my matrix because it wasnt running long enough on a small 125cc tank (its been replaced with a go .21 7p ) and im just wondering would it make a huge difference if i put it into the truck.

If you put the engine into a truck, it's going to get even less runtime. The only way to know which will be faster will be to try both of them out and see which one has the characteristics that will help you the most on the track. Although one may be faster, the other may be quicker. On a tight track, I'd take the quicker motor.

trucks have bigger fuel tanks and so longer runtimes...

I know that trucks have larger fuel tanks, but that doesn't change the fact that the engine is going to consume more fuel if run in a truck. I know plenty of guys that runs .21s in their truggies because of fuel consumption.

ahh rite, well fuel consumption isnt that big a deal, at mi track we have 5 min heats and 10 min mains, and you fill up half way on the main so thats easy..

if you ran a good 21 with a restrictor you could pull that main off without a stop. guys have been pulling 10:30 - 11 minute runtimes at our track.

is a restrictor like wee plastic sleve the you put on the air intake on the carb? if so then there is one on my go .21 (i havent ran it in yet so dont know what runtimes it does) if it isnt then what is that bit of plastic?
